Carbon sequestration

Theme co-ordinator: Bjarni D. Sigurdsson

The forest ecosystem stores significant amounts of carbon in the biomass of trees and in the soil. These soil and biomass stores of carbon are greatly affected by forest management and harvesting intensity through changes in the standing stock of wood and soil carbon dynamics. Following the ratification of the Kyoto Protocol there has been increasing focus on possibilities to sequester more carbon in biological systems and to use wood for energy production. There are many indications that the forests sequester carbon from the atmosphere, thereby providing a significant environmental service to society. The ability to mitigate atmospheric CO2 is therefore an important part in evaluations of the sustainability of various types of forest management. The potential for increased carbon storage relates to management options such as thinning intensity, rotation length, drainage regime, tree species, and silvicultural system (e.g. target diameter harvesting systems vs. clear-cut systems). The emission/
consumption of other greenhouse gasses such as methane and nitrous oxide are considered as well.
